At one time a thirty-two building complex, employing 3000 people, today the area is home to only a handful of building which have been converted into the B&O Railroad Museum.  The most well-known of these buildings is the former passenger car shop, or roundhouse.

The roundhouse (actually a 22-sided polygon) is 123 feet high and 235 feet in diameter.  It was equipped to handle / house 22 cars at once.  In 2002 the roof collapsed due to excessive snow loads, but it was restored and reopened in 2004.
